Hgh Fragment 176-191 — reference

The C-terminal fragment of growth hormone associated with fat metabolism, without the growth-promoting portion of the molecule.

Regulatory statusNot FDA-Approved
Published half-lifeShort — minutes (structurally related to AOD-9604)
Evidence levelLimited data
CategoryOther

Regulatory status

Not FDA-Approved. Not FDA-approved. This is the same region of the hGH molecule that AOD-9604 is based on — AOD-9604 is a modified version of it that reached human trials.

Reported cautions

⚠ Worth knowing. The trials on the modified version (AOD-9604) did not show significant weight loss versus placebo, which is the most relevant human evidence available for this fragment. Does not raise IGF-1. Banned by WADA.

Pharmacokinetics

Published figures give an elimination half-life of Short — minutes (structurally related to AOD-9604). —

This figure is tagged Limited data in our evidence system. The available data does not support a confident single figure, so this entry is flagged accordingly. Read any curve built from it as illustrative only. You can see the shape this implies between doses in the Half-Life Visualizer, and compare it against every other compound in the Half-Life Data Table. Our sourcing page explains what each tier means.

Remember that an estimated curve is a model built from a population figure, not a measurement of your blood. Individual clearance varies, and for depot injections the figure describes release from the injection site rather than the compound clearing. Half-life explained →

What Peptide Plug does and does not publish

This page carries regulatory status, general context and published pharmacokinetics. It carries no dose, frequency or cycle information — that is a deliberate editorial line, because dosing is a clinical decision rather than reference data. We also do not sell, supply, source or link to vendors for any compound.
